About OctoPrint

OctoPrint is a web interface for controlling consumer 3D printers. It runs as a small server attached to the printer, typically on a Raspberry Pi, and lets you manage prints from any browser on your network instead of working at the printer itself.

The project is free software distributed under version 3 of the GNU Affero General Public License and is written in Python. It is extended through an official plugin repository, supported by documentation, a FAQ, a community forum that doubles as a knowledge base, and a Discord server. Development is funded by community supporters who contribute regularly.

Most users install it through OctoPi, a distribution built for the Raspberry Pi, and then follow the online documentation for setup. Because it is self-hosted software that you run on your own device, no vendor account is needed to use it with a printer.
